Ohio Power Siting Board

Welcome to the Ohio Power Siting Board.  Our mission is to support sound energy policies that provide for the installation of energy capacity and transmission infrastructure for the benefit of the Ohio citizens, promoting the state's economic interests, and protecting the environment and land use.

Before construction can begin on any "major utility facility" or "economically significant wind farm" within the state of Ohio, a Certificate of Environmental Compatibility and Public Need must be obtained from the Ohio Power Siting Board.

A "major utility facility" is defined as:

  • An electric generating plant of 50 megawatts or more;
  • An electric transmission line of 125 kilovolts or more; or
  • A gas or natural gas transmission which is more than nine inches in outside diameter and is designed for, or capable, of transporting gas at pressures in excess of 125 pounds per square inch.

An "economically significant wind farm" is defined as:

  • Any wind farm of 5 megawatts or more but less than 50 megawatts.
